I am 88 and just made a virtual appointment with my internist because I am constantly fatigued. The slightest effort exhausts me and I walk very slowly because I don't have the energy to speed up. I especially notice weakness in my legs. After treatment for prostate cancer Lupron destroyed my body's ability to create testosterone so I have very little, 15, where most men have in the 300s or more. Is that the issue or is something else going on? I've decided I need to know and made the appointment.
